This is my second pc build. I already purchased the motherboard - z87n-wifi, ram - corsair vengeance 4gb single module, psu - silverstone st45sf, and my case Lian li pc-09 (modded, cannot fit ATX PSU anymore) I am having problem with my budget. I am looking to get i5-4670k but without a graphics card, if I will get the i3-4130 I could get a graphics card like GTX 650 which do you prefer? If I get the i5 I can overclock my pc but which cooler do you prefer? many said I should get a water cool, this is my first time please help me.
